►Description

 

      Barium carbonate is a white fine powder.

   

     Barium carbonate (BaCO3), also known as witherite, is a chemical compound

 

used in rat poison, bricks, ceramic glazes and cement.

 

     Barium carbonate is insoluble in water and soluble in most acids, with the

 

exception of sulfuric acid. Barium carbonate has a specific gravity of 4.275. Barium

 

carbonate is toxic by ingestion.

 

 

The mineral is named after William Withering, who in 1784 recognized it to be

 

chemically distinct from barytes. It occurs in veins of lead ore at Hexham in

 

Northumberland, Alston in Cumbria, Anglezarke, near Chorley in Lancashire and a

 

few other localities. Witherite is readily altered to barium sulfate by the action of

 

water containing calcium sulfate in solution and crystals are therefore frequently

 

encrusted with barytes.

 

• It is the chief source of barium salts and is mined in considerable amounts in

 

Northumberland.

 

It is used for the preparation of rat poison, in the manufacture of glass and

 

porcelain, and formerly for refining sugar.

 

It is also used for controlling the chromate to sulfate ratioinchromium electroplating

 

baths.

► Production method 

 

 

 Carbonation method: 


BaS + CO2 + H2O→ BaCO3↓+ H2S↑

 

 

BaS + (NH4) 2CO3 → BaCO3 ↓ + (NH4) 2S
 

Reaction equation:


BaS + CO2 → BaCO3 ↓ + H2S ↑

 

Metathesis method. Reaction equation:


BaCl2 + NH4HCO3 + NH4OH → BaCO3 ↓ + 2NH4Cl + H2O
 

Reaction equation:


BaCO3 + 2NH4Cl → BaCl2 + 2NH3 + H2O + CO2


BaCL2 + (NH4) 2CO3 → BaCO3 ↓ + 2NH4Cl

 

 

 

 

►Application 

 

     

(1) Barium carbonate is mainly used for the manufacture of optical glass, funnels,

 

and barium magnetic materials, the manufacture of other barium salts, ceramic,

 

enamel, paint, welding rod feed.
 

(2) It is important chemical raw materials for the production of funnels, magnetic

 

materials and advanced optical glass.
 

(3) It is used for fireworks, flares preparation, also used for auxiliary material of

 

ceramic coatings and optical glass.
 

(4) It is used for the manufacture of electronic ceramics, PTC thermistors,

 

capacitors and other electronic components.
 

(5) Barium carbonate is mainly used for the manufacture of optical glass, CRT

 

glass, and barium magnetic materials and capacitors,

 

(6) It is also used for carburizing steel and metal surface treatment. It is the raw

 

material of manufacturing other barium salts and ceramic, enamel, pigments,

 

paints, rubber, electrode.

 

(7) It is also used as rodenticides and purifying agent, oxidation catalyst.

 

 

►WARNING!

 

 

Emergency Overview


   Harmful if swallowed. Use personal protective equipment. Ensure adequate

 

ventilation. Wash off immediately with plenty of water for at least 15 minutes. Get

 

medical attention immediately if symptoms occur. Rinse immediately with plenty of

 

water, also under the eyelids, for at least 15 minutes. Obtain medical attention.
